## Best for
Coding agents that should verify their changes in the running mobile app, not only in unit tests.

## About agent-device
agent-device from Callstack gives coding agents a live feedback loop on real apps: iOS, Android and HarmonyOS simulators, emulators and devices, plus tvOS, Android TV, web, macOS and Linux. Agents read token-efficient accessibility snapshots, act through refs and selectors and save evidence for review, and it coordinates device access across parallel agent worktrees. It ships as a CLI, a built-in MCP server and a typed Node.js API.

## Install

```
npm install -g agent-device@latest
```
